In this study, we investigated the feasibility of using independent component analysis (ICA) for the isolation of cortical activation associated with affective subject perception of preference during natural, continuous, audiovisual stimuli, and examined the existence of group-trend within that cortical activation. We hypothesized that there would be statistical correlation between the trends of blood oxygen level dependent (BOLD) signals and individual subject perceptions. We also hypothesized that the identified neural substrates would reveal the group-level spatio-temporal features of the neural correlates of subjective perception induced by natural, continuous, audiovisual stimuli. We found both our hypotheses to be true, with separate independent components identifying unique functionally connected areas of activation for the affective subject percepts of preference.
